Specification of Letters Patent.

-Patented Nov.'3, 1914.

Application filed November 14, 1904, Serial No. 232,683. Renewed March 13, 1912. Serial No. 683,610.

To all whom it may concern Be it known that I, HEBER C. PETERS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new 7 and useful Improvements in Adding-Machines, of which the following is a specification.

In the operation of adding machines capable of simultaneously printing several figures to produce a desired number, it is often desirable to be able to print numbers which shall not be accumulated while other numbers printed before and after the excepted number are to be accumulated.

The object of my invention is to provide means which, in general, shall be automatically dependent upon the manipulation of the keyboard for eliminating or accomplishing the function of the accumulating mechanism, the arrangement being such that, under ordinary circumstances, when any key of certain predetermined banks of keys (or in another type of machine any key representing a predetermined value position) shall have been operated, the accumulating function of the accumulator will be automatically eliminated.

A further object of my invention is to provide an interfering means by which the eliminating effect of certain keys or banks of keys of the machine upon the accumulator may be prevented, whereby, under such conditions, the machine may be operated in the ordinary and usual manner throughout its entire range, the accumulator operating in the usual manner.

A further object of my invention is to so combine the last-mentioned interfering means with controlling means by which the machine may be made either split or complete in the manner fully described and claimed in my pending application, Serial Number 221,655.

The accompanying drawings illustrate my invention as applied to a Burroughs adding machine, the general construction and arrangement of which is fully described in Burroughss Patents Nos. 504,963 and 505,078 issued on September 12, 1893.

Figure 1 is a side elevation of so much of such a machine as is essential to illustrate my invention; Fig. 2 is a detail of certain arts shown in Fig. 1 in different positions;

ig. 3 is a transverse section of parts shown m F g. 1; Fig. 4'is a detail of the means for changing the machine from a split to a complete machine or vice-versa, and Fig. 5 is a detail of the automatic means for returning the accumulator to normal.

In machlnes of the type illustrated, as heretofore constructed, the depression of any one of the keys 221 in any of the banks will cause the bell crank lever 217 connected therewith to swing and thus slide upward and forward the, slide 214 relating to the bank of keys in which the operated key belongs, the said slide 214 being held in its forward position by means of a catch 228. The movement of the bell crank lever 217 pulls the corresponding stop wire 270 forward in position to serve as a stop to limit the downward subsequent movement of the toothed sector or segment 610, one of which segments is carried by each of the typecarrying levers 611. Upon the operation of the operating handle 367, subsequent to the depression of any desired keys 221, the lever 813 is first moved in the direction indicated by the arrow in Fig. 1, thus bringing the swinging pawl 821 attached to said lever into engagement with the pin 913' of the T lever 913, and swinging said lever to the position shown in dotted lines in Fig. 1. This movement of the T lever 913 moves the interference link 914 to the position indicated in dotted lines in Fig. 1 and in full lines in Fig. 5. The link 914 is provided upon the upper side of its free end with a notch 914, adapted to receive a pin 910 carried by the accumulator carriage 910 so that when the link 914 is shifted to the position shown in dotted lines in Fig. 1, the accumulator frame or carriage 910 will be swung upon its pivot so as to thus withdraw the accumulator wheels or pinions 916 from mesh with their segments 610. Further movement of the operating lever allows the support 614 to move downward thus freeing all the type arms 611 so that the segments 610 are free to move downward, each of said segments moving downward until stopped by engagement either with the upper or zero stop or by engagement with the operated or pulled-in stop wire 270. The downward movement of the segment 610 under such conditions can cause no movement of the accumulator pinions 916, but, as the operating lever is returned, the lever 813 swings in the direction indicated by the arrow in Fig. 2, and the swinging pawl 821 engages the pin 913 of the lever 913, and returns this lever to the position shown in full lines in Fig. 1, thus returning the accumulator pinions 916 into mesh with the segments 610 so that said segments, as they rise to normal position, will cause an appropriate advancement of the associated accumulator pinions. When a total is to be taken, this operation is reversed by depressing the total key 265 and thereby rocking the bell crank lever 227 which, through link 911, throws link 914 downward until its lower lug 914 lies immediately above the pin 910" carried by the lower side of the accumulator carriage 910. When the swinging of lever 813 takes place thereafter in the direction indicated by the arrow in Fig. 1, the movement of the link 914 to the right causes no movement of the accumulator carriage, and the accumulator pinions 916 thus remain in engagement with the segments 610, and thus control the amount of downward movement of each of said segments, thereby predetermining the total position of the type 618 in a manner thoroughly described in the patents already referred to. When the lever 813 returns under these conditions in the direction indicated by the arrow in Fig. 2, the pawl 821 engages pin 913", and thus draws lug 914 of link 914 to the left (in Fig. 1) so as to thus engage pin 910" and swing the accumulator pinions 916 to the positions shown in dotted lines in Fig. 1, as the segments 610 return upward.

Thus far the parts described are common and well known, and the operation has been merely referred to in order to show the results to be accomplished in the present invention. It will be noticed that the accumulation of any item may be prevented by causing the accumulator pinions 916 to remain out of mesh with the segments 610 during both the downward movement and the upward movement, and I accomplish this result in the following manner: Arranged immediately beneath the rear ends of the slides 214 is a shaft 202%, and upon this shaft 1 pivot a depending arm 87 O. This arm is provided at its lower end with a transverse finger or pin 871'which is arranged to be thrown over into the position shown in Fig. 2 where it will serve as an interference for the pawl 821 so that said pawl on its return stroke cannot engage pin 913 of the T lever 913. In order to control the position of the pin 871, I provide the arm 870 with a cam 872 which is held, by a spring 87 3, in engagement with a pin 867 carried by the dash pot 867, which dash pot is connected with the lever 813. With the construction described, the arm 870 would swing to the right in Fig. 1 upon each operation of the operating lever 367, and in order to prevent such operation, except when it is desired, I provide the arm 870 with a catch 874 which lies normally behind the hooked end of the bell crank latch 875 pivoted on theshaft 200.

If the first four banks of keys, 2'. e., the four banks at the left, are to be arranged 'so that operation of any key therein will cause the elimination of the accumulating function, I swing, at an intermediate-point upon shaft 200, an arm 876, (Fig. 3) which corresponds to the lower arm of the bell crank 875, and connect these two arms by a rod 877 which thus extends beneath the slides 214 of the selected key banks. Each of these slides is then provided with a earn 214 adapted to engage the rod 877 and swing the catch 875, to the position shown in Fig. 2, whenever any key in any of the first four banks is depressed. While in the present instance the rod 877 extends beyond or to the right of the fifth key bank counting from either side of the keyboard, it will be understood that such particular key bank has no control of or cooperation with such rod inasmuch as the slide 214 corresponding therewith is not provided with any depending cam lug as are the slides of the four key banks to the left thereof, it being understood that such rod is so extended solely for the purpose of enabling the end arm 87 6 to be pivoted or swung upon the shaft 200 at a more convenient point than between the fourth and fifth key banks counting from the left of the keyboard. In order to make the operation of these keys as light as possible, the arrangement of pin 867 with relation to the cam 872 is such that when the parts are in normal position, as shown in full lines in Fig. 1, the hook of the catch 875 is slightly spaced from the rear face of the catch 874 so that in the depression of any of the keys of the first four banks, only the unbalanced weight of the catch 875 is added.

Whenever the arm 870 is released from detention by latch 87 5 and the dash-pot 867 moves downward by the operation of the machine, the pin 867', as it moves downward, permits spring 873 to draw arm 870 over, maintaining cam 872 in contact with the pin. This movement of arm 870 should take place during the early portion of the downward movement of the dash pot, and assoon as it has been accomplished the pin 867 passes behind a cam 880 so as to thus retain the arm 870 in its new position against anypossibility of displacement. The pin 871 of the arm 870 in this new position lies closely adjacent and parallel with pin 913" of the lever 913, in the manner already described. It is readily apparent that when the dash post is moved downward without a preliminary lifting of the catch 875, the movement of arm 870 will be very slight indeed, and only the amount permit- .ted until the catch 874 comes in en agement with the hooked end of the latch 8 5.

For a clear understanding of my invention and its purposes and results, one complete operation of the machine will be described and the sequence of movements thereby made apparent, as follows: Preliminarily it may be stated that the interfering arm 870 is always spring pressed by the spring 873 toward the right (Fig. 1) to a position of interference with the pawl 821 for the purpose of eliminating the accumulating function of the accumulating mechanism but that such arm is restrained against such movement by the pin 867 and by the latch 875, with the result that although the machine is operated and the dash pot 867 and the pin 867 thereon is thereby lowered, the arm 870 remains in its inactive position shown in Fig. 1, so long as the latch 875 remains in engagement with the hook 874 on the upper end of said arm. Now starting with the parts in the normal relative positions indicated in Fig. 1, it will be assumed that one of the keys in any one of the four banks or rows of keys of the highest denominations, that is the four banks on the left hand side of the keyboard has been operated. In the present instance where the machine is of the split type such four banks are those comprised in the left hand section of the machine. The depression of this particular he so selected causes, as usual, the rearward sliding of the slide bar 214 corresponding with its bank or row but as each of the slides of this group of key banks is provided with a depending lug 214', such rearward movement of the slide will cause a rearward rocking of the rod 877 which lies in the path of movement of such lug. As a result, the bell-crank shaped latch 875 which is connected with said rod will be raised to a position of disengagement with the hook 874, as illustrated in Fig. 2.

The restraint on the interfering arm 870, so far as the latch 875 is concerned, is now removed but such arm is still under restraint by reason of the pin or stud 867. The particular stop wire 270 corresponding with the key operated has, of course, been pulled rearwardly so that upon the forward stroke of the operating handle or main operating shaft, the rack or segment 610 corresponding thereto is permitted to descend until stopped by said wire. As usual in a Burroughs machine, the accumulator frame 910, upon the initial movement of the oper-.

ating handle, is swung rearwardly to disengage its pinions 916 from mesh with their respective racks or segments 610, such swinging of the frame, being occasioned, in the Well known way, by the forward reciprocation of the pitman or link 914 through the medium of the lever 913, pin or stud .ated, the racks or segments 610 will ascend while the pinions 916 are out of mesh so that no accumulation takes place. In other words, the accumulating mechanism has been rendered inoperative or its function eliminated. The cause of the non-return of the link 914 is the interference with the pawl or wipe plate 821 upon its return stroke, for upon the forward movement of the operating handle or main operating shaft the dash pot 867 together with its pin 867 has been lowered, with the result that the arm 870, now no longer restrained, has been rocked forwardly so as to place its pin 871 in the path of movement of the pawl 821 and thereby interfere with a function of the latter which is to contact the pin or stud 913 and return the pitman or link 914.

This pin 871 is contacted by an edge of the,

pawl whereby the latter is rocked to such a position as to be unable to engage the stud 913" and caused to rock forwardly in an inert condition. The pin 867 upon its return movement restores the arm 870 whichis again caught by latch 875. In this manner, the amount or item set up upon the.

keyboard is simply printed and not accumulated, the accumulating mechanism having been automatically rendered inoperative and prevented from accumulating merely by the act of operating this section of the keyboard as described. Thus, the accumulating mechanism is under the control of any one of the value keys in said section or group. If, on the other hand, one of the keys in the other group or section of the keyboard should be depressed, the machine would operate asa regular Burroughs machine, inasmuch as the slides 214 belonging to such other or right hand section of the keyboard are not arranged to cooperate with the rod 877 or with the interfering arm 870 so that the accumulating mechanism not being interfered with performs its regular functions in the well known way.

Under some circumstances, it will be advisable in a machine of this type to enable the operator to prevent the automatic elimination of the accumulating function of the machine, and this is es ecially true in that type of machines described and claimed in my pending a plication No. 221,655, alreadv referred to, w ere the machine may be readily changed from a split machine to a complete machine" and vice versa. In such a machine, the printing type 618 are actuated by means of hammers 715, the operation of which is fully described in Patent No. 575,078, already referred to. Each hammer is actuated by means of its lever 716 which is normally held against action b means of one of the detents 717. These etents 717, in the type of machine shown in the patent just re erred to, are each provided with a tail 0? which overhangs the heel d of the adjacent detent to the right so that when anyone of the detents 717 is operated it will automatically cause the operation of all of the detents to its right, thus autO- matically printing the zeros to the right of any value figure. The detents are released by means of the pawls 718 which cooperate with the sectors 611 in the manner fully described in the patent referred to.

Whenever a split machine is desired, it has been heretofore customary to omit the tail d from an intermediate detent 717", and in my pending application already referred to, in order to cause an automatic transfer across the gap thus produced, I provided, to the left of the pawl 718 which engaged the detent 717, a pawl 718 which is normally held out of action, Fig. 4 in such construction, the detent 717 to the right of detent 717 will only be engaged by its pawl 718 when the alined sector 611 has been caused to move upward, by reason of the operation of one of the value keys 221 in the key bank relating to this sector, a distance sufiicient to withdraw its shoulder 31' from the path of movement of the inner end of this pawl 718. If, however, the operator desires to secure the automatic transfer of the zero-printing mechanism beyond the gap formed by the detent 717, the key 297 is depressed. This key has its shank connected to an arm 296 carried by a shaft 293 and this shaft carries, in alinement with the pawl 718*, an arm 792 conected by a spring 794 with a cam arm 790. This cam arm 790 is arranged to be projected into the path of movement of a pin 718" carried by pawl 718 so that when the cam finger 7 90 is thus permitted to project into the path of movement of said pin, and the shaft 704, which carries the pawls 718 and 718", is moved to the right in Fig. 4 in the manner described by Patent No. 505,078, the pawl 718 will be moved down (as its companion 718 is moved up), so as to engage the detent 717 and thus withdraw it from the corresponding actuator 716 and thus cause the operation of the hammer 715 alined therewith. The automatic transferring being thus accomplished, the machine is made a complete machine instead of a split machine.

Describing more in detail the mechanism which controls the transferring of the hammer action across the gap or line of split- 611 and the later pawl being under the control of manually operated means whereby the same is placed in operative position with respect to its detent at the will of the operator. According to the illustrated construction, the machine is normally split and adapted to be changed to complete condition by operation of the special key 297. The special pawl 718 is spring pressed by a spring 794 in such manner that its rearward end will be normall held out of the range of the shoulder on te upper edge of its detent 717 with the result that the swinging or rocking of the series of pawls in the well known manner will have no effect upon its detent. When however the key is depressed and the shaft 293 thereby rocked in a clockwise direction, Fig. 4, the restraint of the spring 794 on the cam arm or finger 7 90 is removed and such finger caused to rise against the lower end of the plate 695. Such plate 695 is adapted to be raised whenever any one or more of the sectors 611 on the left hand side of the line of splitting are raised in the operation of the machine in the usual manner, with the result that when so raised, the lower end thereof will clear the cam finger 790 which will thereupon drop downwardly so as to present its cam shaped rearward end to the projection or pin 718*. The result of this adjustment of the cam finger is to cause such pin to ride upwardly thereupon and thereby'cause the rearward end of its pawl 718 to be rocked downwardly into a position of engagement with its detent 717, whereupon such detent will be operated and the gap or line of splitting will thereby be bridged and the hammer action transferred in the same manner as if all of the detents were provided with the tails I). So long therefore as the specific key 297 remains depressed and the cam finger 790 remains in its lower position, the machine will act as a regular or complete machine with the full capacity of keyboard inasmuch as under such conditions the special pawl 718 is acting to cause a transfer of hammer action across the line of splitting whereby the printing of ciphers may be accomplished on the right hand side of any digit in a denominational column on the left hand side of such line of splitis released and permitted to be restored to normal or raised position, the cam .finger will likewise be restored to its normal position indicated in Fig; 4 whereupon the machine again becomes a split machine inasmuch as it is incapable of causing a transfer across the line of splitting.

Withthe machine complete or in a non split condition the probabilities are that the number to be written would be one which should be accumulated, and I therefore find it convenient .to extend the arm 296 beyond shaft 293, and provide it with a pin 296 which may be thrown up into the path of movement of a finger 870 carried by the;v arm 870, thus preventing any movement of the arm 870 when the machine is changed; from a split to a complete machine, but per-'v mitting the automatic movement of the arm 870 to eliminating position when the mar chine is split and any one of the keys in the first four banks is actuated. It will, of course, be readily understood that this-interference with the operation of the eliminating arm 870 may be made entirelyindependent of the split mechanism by providing. a separate and independent key for throwing the pin 296' into the path of movement of the finger 870'.

In operation, if the machine is set for a split machine, 2'. 6., with the button 297 in the position shown in Fig. 1, any operation of any of the keys in the first four banks at the left will not cause the operation of any of the hammers 715 to the right of these four banks, and such operation of any of these keys in the four left-hand banks will shift one of the cams 214 so as to withdraw the latch 875. The subsequent operation of the operating lever 367 will throw the dash potidown and thus permit the pin 871 of arm 870 to swing to the position shown in Fig. 2 so that the pawl 821 on its return stroke will fail to catch pin 913" and thus permit the accumulator pinions 916 to remain out of meshing line with the segments 610 until the pin 354, of the notched sector 311, carried by the shaft 300, engages arm;

919. This arm 919 is attached to the accumulator carriage 910 and thus serves to return the pinions 916 to normal position after the segments 610 have been returned to normal. There is, therefore, no operation of the accumulator pinions 916 under these conditions. If, on the other hand,

none of the keys in the first four left hand: banks is operated, but keys in the righthand banks are operated, there will be no withdrawal of the latch 87 5 and, consequently, no movement of thearm 870 so that the pinions 916 will be given their normal movement such as to permit accumulation of the amount thus indicated. On the other hand, if an amount requiring the use of more than the five right-hand banks is desired, the operator has merely to depress key =29? whereu on the split in the machine is ridged, by 'e use of the pawl 7'18", and the operation of the eliminator arm 870 is prevented \by moving pin 296' into the pa of movement of the pin- 870.

mthepresentlembodiment of my invention as herein shown and described, I have chosen to employ the four banksor rows of keys -.(representing the highest .de-

keys are employed to enable my invention or improvements to cooperate with a split machine, such four banks 10f keys representing the banks .of keys .of the left hand section of the machine or keyboard as the line of splitting, in the particular nine key ,bank machine illustrated, comes between the fourth and fifth key bank counting from left to right. Nor is my invention to be limited to any particular type ,of adding machine.

It will be readily understood :that the details coflconstruction may be infinitely vari without departing from my invention, the broad invention consisting of means controlled automaticalfly by certain keg-banks, or recording .predetermining means or varying the normal action of the accumulator. That is to say, in the drawings I have-Shown a machine where xtlae normal a tion .of the accumulator mechanism is to accumulate every recorded itemand this is accomplished engaging in the cycle of operations. It becomes immediately apparent that the normal conditions of the accumulator might be non-accumulated and the means controlled by part of the key-banks such as to provide for accumulation. Neither is it necessary that there be an actual disassociation between the accumulator and its driving mechbut would be immediately retracted a like amount on the upward movement so that the final result of the accumulator on the item would'be mil. 7

By the use of my invention, I am enabled tr'ol (as to function) of a certain: value; keyor any key of a certain oneor more banks or rows of keys whereby'such accumulating mechanism may be automatically. rendered inopera-i tive-as a result of operating or depressing said key or keys, such mechanism being unaflected-in said respect by the operation of :the remaining key banks. It will'be understood that the numb'er of keys or key banks so capable of controlling the accumulating mechanism is predetermined by. the constructor in a convenient manner. Moreover, the construction and arrangement is such that at the will of the operator, the said interference with the function of the accumulating. mechanism may be prevented and the machine caused to operate in the regular wa'y. Again, when my invention is eni-t bodied in an adding machine of the splittype, such invention may be caused "to 00- operate with one of the sections thereby formed leaving the remaining section to operate as a regular machine. Furthermore,

by the employment of the special key I am enabled, by a single means, to change the ma'chine'from a split to a complete one and also to remove the interference with the accumulating mechanism with the result that the machine will not only accumulate, as usual, but will operate in its full capacity or range.
